Miss Kent reminds her students that every two inches on the model represents 25 feet on the actual statue. Based on Martina's measurements what is the area in square feet of the tablet on the actual Statue of Liberty show your work
Answer:
78.125 ft²
Step-by-step explanation:
The dimension of the tablet is given as:
Length = 1 in
Width = ½ in
First,we need to determine the measurements in feet.
Using the scale measurement:
Scale: 2 in =25 ft
Divide both sides by 2
2 in/2 = 25 ft/2
1 in = 12.5 ft
So, Length = 12.5 ft
Divide the scale measurement by 4
2 in/4 = 25 ft/4
½ in = 6.25 ft
So,
Width = 6.25 ft
Area is calculated as:
Area = Length * Width
Area = 12.5 ft * 6.25 ft
Area = 75.125 ft²

Let the graph of g be a translation 3 units up, followed by a vertical stretch by a factor of 2 and a reflection in the x-
Axis of the graph of
f(x) =3x^2-3x write a rule for g
G(x) =
15 points!!!!
Answer:
The answer is [tex]g(x)= -6x(x-1)+3[/tex]
Step-by-step explanation:
we know that f(x) is written as [tex]3x^{2}-3x[/tex]
to show that the graph is being translated up, vertically stretching, and reflecting across the x axis, we need to factor the function.
[tex]f(x)= 3x^{2}-3x \\ 3x(x-1)\\[/tex]
now we can incorporate the changes to this graph.
multiply 3x by 2 and -1. (2 for a stretch and -1 for a reflection).
[tex]-6x(x-1)[/tex]
tack on the +3 to show a translation of 3 units up.
[tex]-6x(x-1)+3[/tex]
therefore, [tex]g(x)= -6x(x-1)+3[/tex]
hope this helps!
The rule for the graph of g after all transformations of the function f(x) = 3x² -3x is;
g(x) = 6x² + 3x + 6
The graph of f(x) is given as;
f(x) =3x^2-3x
According to the parameters given;
First, the graph of g is a translation 3 units up, therefore, we have;
g(x) = f(x) + 3g(x) = 3x² - 3x + 3Secondly, followed by a vertical stretch by a factor of 2 and a reflection in the x axis.
This means that the graph must be multiplied by 2 and x values containing x be now regarded as -x
g(x) = 6x² - 3x + 6And a reflection in the x-axis yields;
g(x) = 6(-x)² -3(-x) + 6g(x) = 6x² + 3x + 6Ultimately, the rule for the graph of g is;
g(x) = 6x² + 3x + 6.

A contractor has submitted bids on three state jobs: an office building, a theater, and a parking garage. State rules do not allow a contractor to be offered more than one of these jobs. If this contractor is awarded any of these jobs, the profits earned from these contracts are $10 million from the office building, $5 million from the theater, and $2 million from the parking garage. His profit is zero if he gets no contract. The contractor estimates that the probabilities of getting the office building contract, the theater contract, the parking garage contract, or nothing are .15, .30, .45, and .10, respectively.
1. Write the probability distribution of x .
2. Find the mean and standard deviation of x .
Answer:
The probability distribution of x is
Profits in millions (x) Probability of getting contract (P(x))
$10 0.15
$ 5 0.30
$ 2 0.45
$ 0 0.10
The mean is [tex]E(X) = 3.9 millions [/tex]
The standard deviation is [tex]s = 3.01 \ millons [/tex]
Step-by-step explanation:
Generally the probability distribution of x is
Profits in millions (x) Probability of getting contract (P(x))
$10 0.15
$ 5 0.30
$ 2 0.45
$ 0 0.10
Generally the mean is mathematically represented as
[tex]E(X) = x * p(x)[/tex]
=> [tex]E(X) = [10 * 0.15 ] + [5 *0.30 ] + [2 * 0.45 ] + [0 * 0.10] [/tex]
=> [tex]E(X) = 3.9 millions [/tex]
Now
[tex] E(X^2) = x^2 * p(x)[/tex]
=> [tex] E(X^2) = (10 ^2 * 0.15) + (5 ^2 * 0.30) +(2 ^2 * 0.45) + (0 * 0.10)[/tex]
=> [tex] E(X^2) = 24.3 [/tex]
Gnerally the variance is mathematically represented as
[tex]V(X) = E(X^2) - [E(X)]^2[/tex]
=> [tex]V(X) = 24.3 - 3.9^2[/tex]
=> [tex]V(X) = 9.09 [/tex]
Gnerally the standard deviation is mathematically represented as
[tex]s = \sqrt{V(X)}[/tex]
=> [tex]s = \sqrt{9.09[/tex]

In order to convert this equation to Slope-Intercept Form, you must first isolate y.
What is the first step in isolating y?
3x+2y=4
Use Division Property of Equality to divide the equation by 3.
Use Addition Property of Equality to add 2y to both sides of the equation.
Use the Subtraction Property of Equality to subtract 3x from both sides of the equation.
Use Subtraction Property of Equality to subtract 4 from both sides of the equation.
Answer:
use the subtraction property of equality to subtract 3x from both sides of the equation
Step-by-step explanation:
y is on the left so move everything else to the right side
According to the Subtraction Property, both sides of an equation remain equal following a subtracting of the same amount from both sides of the equation
The first step in isolating y in the equation 3·x + 2·y = 4 is the option;
Use the Subtraction Property of Equality to Subtract 3·x from both sides of the equationReason:
The slope and intercept form of the straight line equation is the the equation in the form y = m·x + c
Where;
m = The slope of the equation
c = The y-intercept
The given equation is 3·x + 2·y = 4
To isolate y, the terms containing y, are placed on one side of the equation, while the other terms are placed on the other side as follows;
First step; 3·x + 2·y - 3·x = 4 - 3·x (Subtraction property of equality)
Second step; 2·y = 4 - 3·x
Third step; [tex]\dfrac{2 \cdot y}{2} = \dfrac{4 - 3 \cdot x}{2}[/tex] → y = 2 - 1.5·x (Division property of equality)
y = 2 - 1.5·x = -1.5·x - 2
y = -1.5·x - 2 Equation in slope and intercept form
Therefore, the first step is use the Subtraction Property of Equality to Subtract 3·x from both sides of the equation

Rhoda is asked to graph this system of equations: 5x - 6y = 4 3y + 2x = 7 How many times will the lines intersect? O A. The lines will intersect infinitely many times, because they are identical. O B. The lines will not intersect, because this system has no solutions. O C. The lines will intersect once, because this system has one solution. D. There is no way to tell without graphing the lines first.
Answer:
C. The lines will intersect once, because this system has one solutionStep-by-step explanation:
System of equations:
5x - 6y = 4 3y + 2x = 7The system of linear equations has one solution if the lines intersect, no solution if the lines are parallel, infinitely many solutions if lines are same
Let's put the lines into slope-intercept form to compare
Line1
5x - 6y = 46y = 5x - 4y = 5/6x - 4/6Line 2
3y + 2x = 73y = -2x + 7y = -2/3x + 7/3As we see lines have different slopes so they are different and they intersect once
This system has one solution
Answer:
C. The lines will intersect once, because this system has one solution

The switchboard in a Denver law office gets an average of 8.2 incoming phonecalls during the noon hour on Thursdays. Find the probability that more than 4 calls will be received during the noon hour, on some particular Thursday. Assume calls are independent of each other.
Answer:
The probability that more than 4 calls will be received during the noon hour, on some particular Thursday is 0.9113.
Step-by-step explanation:
The random variable X can be defined as the number of incoming phone calls during the noon hour on Thursdays.
The random variable X describes a finite number of occurrences of an event in a fixed time interval.
The random variable X follows a Poisson distribution with parameter λ = 8.2.
The probability mass function of X is:
[tex]P(X=x)=\frac{e^{-8.2}(8.2)^{x}}{x!};x=0,1,2,3...[/tex]
Compute the probability of more than 4 calls as follows:
[tex]P(X>4)=1-P(X\leq 4)[/tex]
[tex]=1-\sum\limits^{4}_{x=0}{\frac{e^{-8.2}(8.2)^{x}}{x!}}\\\\=1-[0.00027+0.00225+0.00923+0.02524+0.05174]\\\\=1-0.08873\\\\=0.91127\\\\\approx 0.9113[/tex]
Thus, the probability that more than 4 calls will be received during the noon hour, on some particular Thursday is 0.9113.
Write the equation of a line perpendicular to 6y-2x=-8 and passes through the point(-2,1) in slope-
intercept form
Answer:
y = -3x + 17/10
Step-by-step explanation:
First you want to move the 2x to the other side of the equal sign for the proper way of slope-intercept form. Which makes it 6y=2x-8.
You still want to make sure that y is by itself so you divide the whole equation by 6 which makes it y=1/3x-8/6.
We have to find the slope of the a perpendicular line now and to do so, you must take the slope of the given line and make it into the opposite reciprocal.
To do that you take 1/3 and reciprocate it, which makes it 3.
Then flip the sign to make it opposite. Like making a positive into a negative and a negative into a positive. Therefore the slope of the perpendicular line is -3.
Now we must make it past through point (-2,1). To do that you have to adjust the y-intercept. Because of that, the y-intercept is 1.7 or 17/10.
The equation of the slope is y=-3x+17/10
